SPINDLE.

SPECIFICATION forming part of Letters Patent No. 7191,169, dated' May 30, 1905.

y Application filed October 17,1904.. SerialNo. 228,668.

To all whom t may concern:

Be it known that I, MORRIS SUBBER, a citizen of the United States, residing at Woodbine, in the county of Cape May and State of New Jersey, have invented certain new and useful Improvements in Spindles, of which Athe following is a specification.

vsupported upon theXed part of the spindle and the same provided with ball-bearings both at the top and bottom thereof, each ball-bearing being adjustable independently of the other; second, to provide, in connection with such a whirl and its extension, springs or tension-ngers carried by the whirl extension at or near its top and designed to clamp the bobbin to the whirl and its extension and to prevent lateral or vertical movement of the bobbin on the whirl and its extension, and, third, to provide, in such a'spindle, means for lubricating both the upper and lower bearings therefor while in operation.

The nature and scope of my present invention will be more fully understood from the following description,talen in connection with the accompanying drawings, forming part hereof, in which Figure l is. a vertical sectional view of a spindle embodying main features of my invention and of the bobbin supported on the whirl and the extensionof the same of the spindle. Fig. 2 is an enlarged side elevational view of the spindle with the bobbin removed. Fig. 3 is a cross-sectional view on the line 3 3 of Fig. 2, and Fig. 4. is a sectional detail View of the upper end of the whirl extension, showing also the cap-piece with its ferrule.

Referring to the drawings, a represents the fixed spindle, which has near its base a bearing-block a', having an annular groove to receive the balls a2 of a ball-bearing. Surrounding this block avis a whirl b', which in its interior is screw-threaded to be removable from the screw-threaded exterior of said block a', and thus to form with the balls a2 and block a a ball-bearing for the whirl b. The whirl b' is provided with an upwardly-projecting tube or extension which surrounds the upper free end of the` Xed spindle a and is arranged to revolve with the `whirl b around the same. The top of the spindle a is provided with a V-shaped depression a to receive a ball c3, and the tube b of the whirl b extends above the grooved top of the spindle c in the form of a removable cap-block b3, provided .with a V-shaped depression to form, with the ball a3 and top of the spindle c, an upper ballbearing Z2, designed to center and to hold the lwhirl in a central position upon the top of the spindle co. Fitting in the whirl-tube and in a cap-block 3, closing the upper end 0f the whirl-tube are springs CZ, the ends of which are mounted, respectively, in said whirl-tube and in a sleeve b5, and the body of these springs is bellied outto'form a resilient bearing, over which the bobbin e is slipped. These springs d form a rigid connection for the upper end of the bobbin on the whirl-tube and prevent lateral as wellas vertical movement of the bobbin on said whirl and its tube. The sleeve b5, which looselysurrounds the upper end of the whirl-tube is provided with grooves be, in which the upper ends of the springs d are placed and in which the same are afforded a certain range of movement caused by the pressing inward of the springs 0l by the bobbin e. The cap-block b3 is arranged to be advanced or retracted in an interior screwthreaded portion in the free end of the whirl-- tube and a ferrule j' is arranged to engage the cap-block b3 and to bear down upon the end of the whirltube b and the sleeve b5. The cap-piece b3 may be advanced or retracted in both the ferrule f and the whirl-tube b and when in proper yposition within the whirltube is locked by the ferrule f in said position. through which oil may be introduced from the open top end of the ferrule f to lubricate the upper ball-bearing and the space between the whirl-tube and the fixed spindle a. The

The cap-block b3 has a vertical duct of, o

IOO

lower portion of the spindle a has a vertical duct a* and a transverse duct a5, leading therefrom to the ball-bearing of the whirl b. Oil is forced from a cup 0r reservoir g through these ducts a4 and a to the ball-bearing and the space between the spindle rand the whirl ZJ by advancing the cup or reservoir g upward on the spindle a. To so advance the reservoir, its exterior is screw-threaded and ts into the screw threaded interior of a bracket g', fixed on the spindle a, as clearly illustrated in Fig. 1. Instead of forming the whirl b and whirl-tube separate the whirl b may be provided with an integral tubular extension b.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, a iXed spindle, a whirl-tube surrounding the same, removable means closing the free end of the tube, a whirl carrying ldie whirl-tube, an adjustable ball-bearing interposed between the whirl and the spindle, and a ball-bearing interposed between the removable means and the top of the spindle.

2. In a device of the character described, a iiXed spindle, a whirl and a whirl-tube surrounding the same, a ball-bearing supported at the top of the spindle, a cap-piece adjustable in the top of the whirl-tube toward or away from said ball-bearing, and a ferrule arranged to lock the cap-piece to said whirl.

3. In a device of the character described, a fixed spindle, a whirl and a whirl-tube surrounding the same, a ball-bearing arranged l at the top of said spindle, a cap-piece adjustable in the top of the whirl-tube and constituting one of the members of the ball-bearing, a sleeve surrounding the upper end oi the whirl-tube, and springs having their ends engaging respectively the sleeve and the whirltube and adapted to hold a bobbin on the whirltube and whirl without lateral or vertical movement of the bobbin thereon.

4. In a device of the character described, a iiXed spindle, a whirl and a whirl-tube surrounding the saine, a perforated cap-piece in the whirl-tube, an upper ball-bearing engaging the cap-piece and supporting the whirltube upon the top of the spindle, a lower ballbearing supporting the whirl at the base of the spindle, an oil cup or reservoir surrounding the spindle and ducts arranged in the spindle for lubricating the ball-bearing of the whirl.

5. In a device of the character described, a iixed spindle having a groove in its upper end, a ball supported in said groove, a whirl anda whirl-tube surrounding said spindle, a cappiece adjustable in the top of said whirl-tube and grooved to receive the ball of the spindle, and said cap-piece bearing upon said ball to support and center the whirl upon said spindle.

In testimony whereof I have hereunto set my signature in the presence olE two subscribing witnesses.
